Abstract

Background: Bone resorption patterns in the posterior maxilla may preclude the placement of implant lengths ≥10mm. In order to attain adequate height for implant placement below the sinus floor, additional bone grafting may be necessary. After sinus bone augmentation, a 6 to 9 month healing period is often required prior to implant placement, which prolongs the healing time and increases costs to the patient. Purpose: The purpose of this retrospective study is to evaluate the number of short-plateau design dental implants, 8 mm or less in length, in maxillary sinus augmented sites with either an internal sinus lift procedure or a sinus transport procedure with or without bone grafting. Materials and Methods: A retrospective chart review was accomplished on patients that received a short plateau design dental implant 8mm or less in length from January 1, 2008 to December 31, 2009. All dental implants were placed with either an internal sinus lift or a sinus transport with or without the use of grafting materials. Descriptive statistics were gathered. Results: Sixty-three out of 67 dental implants were included in the study. Fifty dental implants were placed with an internal sinus lift compared to 13 dental implants placed with the crest transported through the sinus. The bone quality assessed at each site of placement ranged from type III (7.9%) to type IV (88.9%). Bone graft materials included SynthoGraft™ only (65.1%), SynthoGraft™ and autogenous bone (6.3%), autogenous bone only (9.5%), or no bone graft material (17.5%). The success rate of implant osseointegration at the time of uncovering was 98.4%. Implant loading ranged from 234 to 1,135 days in 49 dental implants that were restored. Ten (15.9%) implants incurred complications related to the restoration. Eighty-four percent did not have any implant complications. Conclusions: This preliminary study demonstrates that placing short dental implants 8mm or less at the time of sinus augmentation may be possible. Minor complications may be experienced with these procedures. However, long-term data on survival and performance of short dental implants is needed.
